Creators Ari Last and Adrian Murdock, who describe themselves as "entrepreneur dads", have joined forces with Surrey women's network She.Space to help launch the service, which allows parents to find a baby sitter within 43 seconds.

The app places a strong emphasis on trust, using parents' phone book and Facebook accounts to show how they are connected to a potential sitter through friends and the local community, as well as allowing parents to read reviews of each sitter before booking.

Bubble also uses its own background check to clear potential sitters before allowing them onto the app, regardless of whether they also have a DBS certificate, which most do.

The background check looks at more than 5 million records in the UK and worldwide, including criminal watch lists and adverse media reports. Once checked, the sitter's details remain on the database and the company is alerted to any possible match in the future.

Dahlia Dayani, who lives in West Hampstead and already uses the app, said Bubble has been "a real life-changer", especially when she needs to go out at the last minute without having to take her children with her.

She said: "It's great to have so much choice, and the ability to check on people's backgrounds as leaving your children with someone you don't know, as well as having them come into your house, can be quite daunting, but I can't fault Bubble.

"The background checks are co-ordinated well and all the sitters I've had have been very experienced. I would definitely recommend the app, and all my initial first-time nerves were settled immediately."

The app allows parents to review babysitters

Mr Last said: "As parents we know that when it comes to finding a brilliant babysitter for our kids, nothing is as powerful as a personal connection or recommendation.

"Our aim with Bubble is to make finding trusted childcare - any time, anywhere - an easy and fun experience.

"Bubble is providing parents - working mothers especially - with the flexible childcare solution they need in order to get back to, and get on with work.

"We're excited about rolling out in Surrey and we've got a great local partner in She.Space to help us do that."

Co-founders Ari and Adrian designed the app upon becoming dads

Liana Wilson-Fricker, co-founder of She.Space, said: "At She.Space we work with, and speak to, brilliant, entrepreneurial mums every day who struggle with the issue of finding someone to look after their kids.

"Which is why we were so keen to work with Bubble in bringing the app to Surrey.

"It's an amazing tool for finding trusted, affordable and flexible childcare, and can help parents better juggle both our work life and social life too."
